.mobi domains

The .mobi domain is a long-established extension created to signal mobile-friendly websites, dating from the early days of the mobile web. While responsive design has since made a dedicated mobile extension less of a technical necessity, .mobi remains a clear, recognizable choice for mobile apps, services, and sites that want to emphasize a phone-first experience. Registration is open to anyone worldwide with no restrictions. The extension still communicates its purpose at a glance, which can be useful for QR-code landing pages, app companions, and mobile services. For a project where the mobile experience is the point, or a brand that wants an available, meaning-rich alternative to a generic extension, .mobi offers a short name with a built-in message.
